| Question ID:640-505qod25 |
| Which of the following memory types is used to hold the router IOS image? |
| A) | ROM | | B) | Flash | | C) | RAM | | D) | NVRAM |
| Correct
answer: B |
Explanation:
Flash is the memory type used to hold the router IOS image. A special type of EEPROM that can be erased and reprogrammed in blocks instead of one byte at a time. Many modern PCs have their BIOS stored on a flash memory chip so that it can be updated easily if necessary. Such a BIOS is sometimes called a flash BIOS. Flash memory is also popular in modems because it enables the modem manufacturer to support new protocols as they become standardized.
